Cantilever beam multi-buffering mechanism

The invention discloses a cantilever beam multi-buffering mechanism, and belongs to the technical field of foundation engineering machinery. Comprising a rack and a cantilever beam installed on the rack, a horizontal sliding rail parallel to the cantilever beam is fixed to the lower side face of the cantilever beam, and a horizontal sliding block in sliding fit with the horizontal sliding rail is fixed to the rack; a vertical sliding rail perpendicular to the horizontal sliding rail is fixed to the outer suspension end of the cantilever beam, and a vertical sliding block is installed on the vertical sliding rail in a sliding mode. A rubber pad is arranged on the side, away from the cantilever beam, of the vertical sliding block, a connecting block is arranged on the side, away from the vertical sliding block, of the rubber pad, and the connecting block, the rubber pad and the vertical sliding block are fixedly connected into a whole. According to the cantilever beam system, multiple buffering designs of stati
